[bug-gawk] Fwd: [Bug 820550] New: gawk: getline in BEGIN skips 2 lines

[James Hogan]

Hi,

I just reported this bug to redhat bugzilla.

I notice there's something similar on this list "getline difference
from gawk versions >=4.0.0" from 2nd april this year, but my one looks
a bit more clear cut wrong.

Cheers
James

How reproducible:
always

Steps to Reproduce:
{ echo "line 1"; echo "line 2"; echo "line 3"; } | awk 'BEGIN { getline } {
print $0 }'

line 3

Expected results (GNU Awk 3.1.7):
line 2
line 3
